Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a wiring harness bundling and fixing device for RVs. Background Technology

[0002] During the production of RVs, the relevant cable harnesses need to be bundled and fixed, mainly based on safety and functional requirements: driving vibrations can easily cause the harnesses to wear and short-circuit. The bundling device eliminates shaking through mechanical limits, reducing the risk of insulation layer breakage. At the same time, the dual power supply system (low voltage and high voltage) requires the harnesses to be fixed in layers to avoid electromagnetic interference from high current lines that may cause equipment malfunctions and ensure the normal operation of the harness system. The existing cable tie body (bundling part) and connector are generally molded as one piece.

[0003] An existing automotive wiring harness bundling device (notification number: CN219339385U) has at least the following drawbacks:

[0004] In the aforementioned patent, the unlocking of the clip is controlled by a drive block, eliminating the need to cut the cable ties and solving the problem of waste associated with traditional disposable cable ties. This is especially suitable for frequent maintenance scenarios, improving disassembly efficiency. By avoiding the use of scissors, the risk of scratching the wire harness insulation is eliminated, ensuring the reliability of the wire harness. However, the main body and the clip of this bundling device are an integrated fixed structure. When the clip is inserted into the mounting hole on the vehicle body, the size of the mounting hole may be non-standard, making it difficult to use the clip. Custom design is required. Custom designing and reproducing the entire bundling device is quite troublesome and increases costs. Therefore, it is necessary to propose a wire harness bundling and fixing device for RVs to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a wiring harness bundling and fixing device for RVs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wiring harness bundling and fixing device for a motorhome includes a fixing base, a bundling strap fixedly installed on one side of the fixing base, a threaded connector and a mushroom connector provided on the bottom surface of the fixing base, and a replacement component. The replacement component is located on one side of the fixing base and is used to replace the threaded connector and the mushroom connector. The replacement component includes: a first fixing hole, which is opened on one side of the fixing base, a first connecting plate movably sleeved inside the first fixing hole, the bottom surface of the first connecting plate being fixedly installed with the threaded connector, the top surface of the mushroom connector being fixedly installed with the first connecting plate, limit frames fixedly installed on both sides of the fixing base, a support plate fixedly installed on the top surface of the limit frames, two fixing grooves opened on the top surface of the first connecting plate, the fixing grooves being movably sleeved with the limit frames, a fixing ring fixedly installed on the outside of the limit frames, and a disassembly component for removing the bundling strap from the fixing base in the reverse direction.

[0008] As a further embodiment of this utility model, the disassembly assembly includes: a second fixing hole, the second fixing hole being opened on the top surface of the fixing seat, a pressure plate being movably sleeved inside the second fixing hole, and protruding second connecting plates being provided on both sides of the pressure plate, the second connecting plates being fixedly installed with the inner side of the second fixing hole.

[0009] As a further embodiment of this utility model, the support plate is internally fixedly equipped with reinforcing ribs.

[0010] As a further embodiment of this utility model, a plurality of grooves are provided on one side of the first connecting plate, and a plurality of protrusions are provided on one side of the interior of the first fixing hole, wherein the protrusions are movably sleeved with the grooves.

[0011] As a further embodiment of this utility model, chamfered edges are provided on the four sides of the interior of the first fixing hole.

[0012] As a further embodiment of this utility model, the bottom surface of the strapping is provided with several limiting grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By using the threaded connector, mushroom connector, fixing groove, first connecting plate, and support plate in conjunction, the mushroom connector can be replaced. It can be disassembled by moving the support plate and pressing the first connecting plate, and then the new threaded connector can be installed. The operation is relatively simple. When the vehicle body mounting hole is not compatible, only the connector needs to be manufactured separately. There is no need for overall customization, which reduces the complexity and cost of customization and facilitates use.

[0015] 2. By fitting the protrusions and grooves, the first connecting plate is ensured to be horizontally fixed and stable after being inserted into the first fixing hole. The reinforcing ribs enhance the connection strength between the support plate and the limiting frame. After inserting the mushroom connector into the mounting hole using the provided strapping, the head of the strapping is rotated clockwise to fix the wire harness and inserted from the left side of the fixing seat. The limiting groove pushes the pressure plate to rotate, producing a clicking sound. After the bottom of the pressure plate is inserted into the limiting groove, it forms a reverse limiting. When disassembling, the pressure plate is rotated in the opposite direction, and the second connecting plate bends elastically to make the pressure plate disengage from the limiting groove, allowing the strapping to be removed.

[0025] Reference Figures 1-5 A wiring harness bundling and fixing device for a motorhome includes a fixing base 1, a bundling strap 2 fixedly installed on one side of the fixing base 1, a threaded connector 9 and a mushroom connector 8 provided on the bottom surface of the fixing base 1, and a replacement component. The replacement component is located on one side of the fixing base 1 and is used to replace the threaded connector 9 and the mushroom connector 8. The replacement component includes: a first fixing hole 3, which is opened on one side of the fixing base 1, a first connecting plate 7 movably sleeved inside the first fixing hole 3, the bottom surface of the first connecting plate 7 being fixedly installed with the threaded connector 9, the top surface of the mushroom connector 8 being fixedly installed with the first connecting plate 7, limit frames 4 being fixedly installed on both sides of the fixing base 1, a support plate 6 being fixedly installed on the top surface of the limit frame 4, two fixing grooves 10 being opened on the top surface of the first connecting plate 7, the fixing grooves 10 being movably sleeved with the limit frame 4, a fixing ring 5 being fixedly installed on the outside of the limit frame 4, and a disassembly component, which is used to remove the bundling strap 2 from the fixing base 1 in the reverse direction.

[0026] In use, when the user needs to replace the threaded connector 9 or other types of plugs to fit into different sizes of mounting holes, the user lifts the fixing base 1 and manually moves the support plate 6 to slightly rotate the limiting bracket 4 to the left. The rotation is achieved using the bent part of the limiting bracket 4 (the limiting bracket 4 and the bent part are pre-molded as a single piece, allowing the limiting bracket 4 to bend slightly without breaking; this is not a post-bending process, and the bent part is located near the center of the limiting bracket 4). The fixing ring 5 has a certain elasticity and is... After being stretched, the elasticity of the fixing ring 5 maintains the reset thrust on the limiting frame 4. When bending, the bottom of the limiting frame 4 moves out of the fixing groove 10. Pressing the side of the first connecting plate 7 with the thumb causes it to move out of the first fixing hole 3, completing the disassembly of the threaded connector 9. Insert the first connecting plate 7 connected to the new mushroom connector 8 or other connector into the first fixing hole 3. Move the support plate 6 to push the first connecting plate 7. After releasing the support plate 6, the limiting frame 4 resets and enters the fixing groove 10 under the push of the fixing ring 5 to complete the fixation of the mushroom connector 8.

[0027] In this embodiment, the disassembly assembly includes: a second fixing hole 14, which is opened on the top surface of the fixing base 1. A pressure plate 15 is movably sleeved inside the second fixing hole 14. The pressure plate 15 has protruding second connecting plates 16 on both sides. The second connecting plates 16 are fixedly installed with the inner side of the second fixing hole 14.

[0028] In use, after inserting the mushroom connector 8 into the mounting hole using the provided strapping 2, rotate the head of the strapping 2 clockwise to fix the wire harness and insert it from the left side of the fixing seat 1. The limiting groove 17 pushes the pressure plate 15 to rotate, making a clicking sound. After the bottom of the pressure plate 15 is inserted into the limiting groove 17, it forms a reverse limiting. When disassembling, rotate the pressure plate 15 in the opposite direction. The second connecting plate 16 bends elastically, causing the pressure plate 15 to disengage from the limiting groove 17, and the strapping 2 can be removed.

[0029] In this embodiment, a reinforcing rib 13 is fixedly installed inside the support plate 6, a number of grooves 12 are provided on one side of the first connecting plate 7, a number of protrusions 11 are provided on one side of the first fixing hole 3, the protrusions 11 are movably connected with the grooves 12, chamfers 18 are provided on the four sides of the inside of the first fixing hole 3, and a number of limiting grooves 17 are provided on the bottom surface of the strapping 2.

[0030] In use, the protrusion 11 and the groove 12 fit together to ensure that the first connecting plate 7 is horizontally limited and stable after being inserted into the first fixing hole 3, and the reinforcing rib 13 enhances the connection strength between the support plate 6 and the limiting frame 4.

[0031] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0032] With the fixed base 1 in place, when the user needs to replace the threaded connector 9 or other types of plugs to fit into different sizes of mounting holes, the user picks up the fixed base 1 and manually moves the support plate 6 to slightly rotate the limiting frame 4 to the left. The rotation is achieved using the bent part of the limiting frame 4 (the limiting frame 4 and the bent part are pre-molded as a single piece, allowing the limiting frame 4 to bend slightly without breaking; this is not a post-bending process, and the bent part is located near the center of the limiting frame 4). The fixing ring 5 has a certain elasticity; after being stretched, the elasticity of the fixing ring 5 maintains the restoring thrust on the limiting frame 4. During bending, the bottom of the limiting frame 4 moves out of the fixing groove 10, and the thumb presses and pushes the side of the first connecting plate 7 to... The threaded connector 9 can be removed from the first fixing hole 3 to complete the disassembly. The new mushroom connector 8 or the first connecting plate 7 connected to other connectors can be inserted into the first fixing hole 3. The support plate 6 can be moved to push the first connecting plate 7. After the support plate 6 is released, the lower limit bracket 4 is pushed by the fixing ring 5 to reset and enter the fixing groove 10 to complete the fixing of the mushroom connector 8, thereby achieving the effect of replacing the mushroom connector 8. The first connecting plate 7 can be disassembled by moving the support plate 6 and pressing it. The new threaded connector 9 can then be installed in the position. The operation is relatively simple. When the vehicle body mounting hole is not compatible, only the connector needs to be manufactured separately. There is no need for overall customization, which reduces the complexity and cost of customization and facilitates use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
